Daily Driving The average number of miles a person drives per day is 24. A researcher wishes to see if people over age 60 drive
less than 24 miles per day. She selects a random sample of 25 drivers over the age of 60 and finds that the mean number of
miles driven is 22.5. The population standard deviation is 4.1 miles. At a = 0.01, is there sufficient evidence that those drivers
over 60 years old drive less than 24 miles per day on average? Assume that the variable is normally distributed. Use the critical
value method with tables.
Part: 0/5
Part 1 of 5
State the hypotheses and identify the claim with the correct hypothesis.
H: H = 24
not claim
H: u < 24
claim
The hypothesis test is a one-tailed
test.

Part 2 of 5
Find the critical value(s). Round the answer to at least two decimal places. If there is more than one critical value, separate
them with commas.
Critical value(s):
Part: 2/5
Part 3 of 5
Compute the test value. Always round z score values to at least two decimal places.
Part: 3 /5
Part 4 of 5
Make the decision.
(Choose one) v the null hypothesis.
